A shrink tunnel or heat tunnel is a heated tunnel mounted over or around a conveyor system. Items (such as packaging ) have shrink film loosely applied; with heat, the film shrinks to fit snugly around the wrapped object.
The cap torque tester is used in the packaging industry to measure the opening or closing torque of the screw cap. Proper torque is required for the cap to perform its functions of maintaining a tight seal. [1] It is a piece of specific quality control equipment that can be placed on the production line or in the laboratory. Several designs ...
Once the machine is started it begins to apply an increasing load on specimen. Throughout the tests the control system and its associated software record the load and extension or compression of the specimen. Machines range from very small table top systems to ones with over 53 MN (12 million lbf) capacity. [3] [4]
A key component of modern torque testers is the digital display. A digital display is used to measure the output signal from the transducer and calculates that reading into a torque value that is displayed on screen. In most cases the display and transducer are contained together inside a housing. This is known as a "Desktop Torque Tester".
Automatic test equipment diagnostics is the part of an ATE test that determines the faulty components. ATE tests perform two basic functions. The first is to test whether or not the Device Under Test is working correctly. The second is when the DUT is not working correctly, to diagnose the reason.
Fixtured "hands" of various designs are used to hold a handle (sometimes two handles for a box). Most common are "jerk testing" by modified drop test procedures or use of the constant pull rates of a universal testing machine. Other procedures use a static force by hanging a heavily loaded package for an extended time or even using a centrifuge.
Heat seal connectors are used to join LCDs to PCBs in many consumer electronics, as well as in medical and telecommunication devices.. Heat sealing of products with thermal adhesives is used to hold clear display screens onto consumer electronic products and for other sealed thermo-plastic assemblies or devices where heat staking or ultrasonic welding are not an option due to part design ...
